Treehouse Club - MASH

Call the function by giving an age to the parameter.

function random _age (age) {Math.floor(Math.random()*age);} random_age();

  • What defines age? A number?
script.js 
function random_age(age) {
  Math.floor(Math.random() * age);
}
random_age();

Correct. :-)

To use the function you would call something similar to: random_age(21);

Jason,

The following from the php documentation describes php data type behavior.

"The type of a variable is not usually set by the programmer; rather, it is decided at runtime by PHP depending on the context in which that variable is used."
